Anisha Malhotra Prof. Lovett Lab Report # 4 Experiment 7&8 1 Bacterial Growth and One Step Burst - T7 Phage I. INTRODUCTION: These experiments helped us learn the factors that were involved in the growth of the bacteria that increased our study towards their genetic‚ physical and metabolic characteristics. We used Escherichia coli and Bacteriophage T7 to identify and analyze their identical life cycle and replication that was involved in their process of growth. As‚ growth for any bacteria

Lung Capacity I. Introduction. The chest contains two lungs‚ one lung on the right side of the chest‚ the other on the left side of the chest. Each lung is made up of sections called lobes. The lungs are soft and protected by the ribcage. The purpose of the lungs is to bring oxygen into the body and to remove carbon dioxide. Oxygen is a gas that provides us with energy‚ while carbon dioxide is a waste product or “exhaust” of the body. | To deliver oxygen to the body‚ air is breathed in through

representatives. Aside from the hard-to-classify Arkarua (a Precambrian animal with Echinoderm-like pentamerous radial symmetry)‚ the first definitive members of the phylum appeared near the start of the Cambrian period. The word "echinoderm" is made up from Greek ἐχινόδερμα (echinóderma)‚ "spiny skin"‚ cf. ἐχῖνος (echínos)‚ "hedgehog; sea-urchin" and δέρμα (dérma)‚ "skin"‚ echinodérmata being the Greek plural form.[2] The echinoderms are important both biologically and geologically.

Chemical Reactions Lab Introduction Four different types of chemical reactions were observed in this lab. Synthesis reactions occur when two different elements or compounds form a more complex compound as shown by equation (1). Single replacement occurs when one element replaces another to form a new compound as shown in equation (2). Double replacement occurs when two different atoms in different compounds trade places with one another to form two new compounds as shown in equation (3).Combustion

Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions. Radioisotope - The nuclei of some isotopes of an element are unstable

Independent Reading Reflection My independent reading goal for this quarter was to read two or more books of a different genre variety. I read two books‚ one fiction and one non-fiction‚ meaning I met my goal. I had to make time to read with a busy schedule making me use my time management skills in bettering me for college level reading. One book I read‚ was Sickened by Julie Gregory. This is a biography so it’s a non-fiction book making this book out of my comfort zone. I am usually not interested
